Puzzled. How to connect Krell SBP 32X DAC to laptop or phone

And now I'm looking at this. Too many options! 

What about HDMI to coax? That's another option. Thank you. 

Oh boy. Okay. I was hoping to now spend that kind of money. I'll see what I can find. 

Thank you!

@e-rock No you can't use that. You need something like this or a Mutec+USB or similar.

Thanks for the help. So I can't just connect this?

You can connect your laptop using a USB/SPDIF converter.
